Application filed May 25,

concern:

Be it known that FRANK E. MoALLIs- R a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Check- Protectors; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others killed in the art to which it appertains to make and use the same.

This invention relates to a perforating or mutilating device which is adapted to form in one of its uses a check protector. The device is of the type in which a sheet of paper may be placed to have the surface thereof indented or perforated so that writing upon the same cannot be altered after such indentation or perforation. If it is at tempted to write upon the check after the ame has been operated upon by the device, the ink will run into the broken parts of the paper and all negotiability of a check so operated upon will be destroyed. It is an object of the invention to provide such a device of extremely simple construction and of such size that it can be readily carried on the person, if desired.

It is a further object of the invention to provide such a device in which a plurality of movable serrating devices are employed so that the same can be brought into vari- 0115.,- degrees of alinement.

These and other objects and advantages cf the invention will more fully appear from the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the difierent views, and in which Figure 1 is a view in side elevation of the device a difierent position of the same being shown in dotted lines;

Fig. 2 is a plan view illustrating the use of the device;

Fig. 3 is a partial view in side elevation on an enlarged scale and Fig. 4c is a view in end elevation as seen from the left of Fig. 1, the same being shown on an enlarged scale and with the perforating rollers pressed together.

Referring to the drwmgs, the device is seen to comprise a member 1, WhlCll, 1n the embodiment of the invention, illustrated, is formed of a flat piece of thin res1l1ent ma- Specification of Letters Patent.

terial bent at its middle portion into substantially U-shape with the arms 1 and 1 thereof slightly diverging and the ends of the arms slightly inturned toward each other at right angles. Mounted upon each of the arms 1" and 1" are U-shaped members 2, the arms of which are of general triangular shape and are formed adjacent their connecting portion with rectangular openings adapted to receive the arms 1 and 1 The bottom or connecting portions of the mem bers 2 thus extend longitudinally of the arms 1 and 1: and have their inner surfaces in contact with the outer surfaces of said arms. The inwardly projecting arms of the members 2 are apertured and have journaled therein shafts 3 upon which are rigidly secured within the arm of the members 2, mutilating rollers 4. These rollers are cylindrical in form and have their peripheries stipple'd, milled or serrated to form mutilating or perforating points. As shown in Fig. 3, in the embodiment of the invention illustrated, the rollers are provided with V-shaped channels arranged at right angles to each other, thereby forming rows of pyramidal projections which are arranged to mesh on the respective rollers to mutilate or perforate the sheet of material placed therebetween.

The use of the device i illustrated in Fi 2. A check or other sheet of material whic is desired to perforate or mutilate is placed between the rollers 4 and the device held in the hand and the rollers moved into contact with the said material. The same can then be drawn through the rollers or the rollers moved along the same, sufficient pressure being placed upon the rollers to uitably operate upon the material. By having the rollers 4 slidable upon the arms 1 and 1 the same can be brought into alinement with each other, as shown in Figs. 1, 2 and 3, or they can be moved more or less out of alinement, thus varying the perforating surfaces which is used. By thus having the rollers relatively movable, ang desired Width of paper up to the full widt of the rollers can be operated upon. The rollers can also be moved to various points along the arms 1 and 1 to suit the convenienoe of different operators. The l.)- shaped members 2 are frictionally held 1n any adjusted position on the arms 1 and 1".

From the above descriptlon it is seen that applicant has providedan extremely simple form of hand check protector or mutilating instrument. The same comprises few parts and said parts can be easily and cheaply made and yet have great strength and durability.

It will, of course, be understood that various changes may be made in theform, details and proportions of the device without departing from the scope of applicant invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.

\Vhat is claimed is:

1. A mutilating in trument comprising a member having slightly diverging arms connectedat one of their end and adapted to move toward and from each other, and a mutilating roller mounted upon each of said arms and disposed between the same with its axis extending longitudinally of said arms, one of said rollers being longitudinally movable with respect to the other.

2. A mutilating instrument comprising a resilient member bent at its middle portion into ubstantially U-shape and a mutilating roller movable longitudinally of its axis mounted upon each of said arms, said rollers being located between the arms and hav ing their a es disposed longitudinally of said arms.

3. A hand check protector having in combination a flat resilient bar bent at its middle portion into substantial U-shape with the arms thereof slightly diverging and having their inner ends inturned toward each other, a U-shaped member slidably mounted upon each of said arms with its connecting portion in engagement therewith and its arms directed inwardly thereof, and a serrated roller member journaled in and between the arms of said last mentioned U- shaped member with its axis extending lon-' gitudinally of the arms of said first men tioned U-shaped member.

4. A hand check protector having in combination a flat resilient member bent at its middle portion into substantially U-shape with the a lns thereof slightly diverging, a U-shaped member mounted upon each of said arms, said last mentioned U-shaped members having apertures in the arms adjacent the connecting portion through which the arms of the first mentioned member pass, said U-shaped members being thus frictionally and slidably mounted upon said arms and a serrating .roller journaled in and between the arms of said last mentioned U- shaped members and disposed between the arms of the first mentioned member.

In testimony whereof I aflix my signature.

FRANK E. MCALLISTER.
